If you are browsing from Europe and have reliability problems hitting this site,
it could be that your network's DNS server has bad defaults for the TTD (Time To Die) on the TCP-IP
network packets. As some backbone internet providers in the UK, US and Ausutralia put the incoming
TCP-IP packets through a a few dozen internal routers, depending on the time of day, DNS caches, etc; the TCP-IP packet
has probably died before it gets here to bluehaze.com.au. Setting a larger default TTD on the DNS
server generally fixes this (it may have to be recompiled into the kernel depending on what operating
system you are using). E.g., in the following default traceroute from Europe, the packets have
bombed near Singapore(?) (did not even make it to Australia as the TCP-IP packets bounced around bbnplanet.net for
a dozen hops) (use traceroute -m 50 to increase the number of hops traceroute reports.

"The Public DNS Service is a public service provided by Granite Canyon Group, LLC. The
Service offers both primary and secondary DNS free of charge to anyone who asks. The
Service maintains UPS protected FreeBSD servers that satisfy DNS queries. The servers are
geographically separated and all are connected to the Internet via 7x24 dedicated lines with
disjoint routes to the Internet's North American backbones. "

BTW - just talking to [Internet Gure Omega (not real name)] and he rang
someone in ITS to ask re hop maximums. Apparently it started out as 16 in
the early days, then went to 30, and now can be more than this due to
smart routers or something.
Re our large number of hops, he drew me a diagram of a "router hotel" which
he said is common. Link comes in from (eg) .au then goes to another router
because this 1st one only handles traffic direct to (eg) .ca, .fr, .za -
this 2nd router similarly doesn't do .uk directly so again it gets passed
onto another one, etc. Basically a case of what happens when you have to
process 200 domains with only 10 or 15 routers in the rack.
Cheers,
Tony
